A typical 1 cup cooked serving of hyacinth beans contains 15.8 grams of protein (8.14 g per 100 g), which makes it a very good source of protein. That covers roughly 32% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
Around 28% of the calories in hyacinth beans come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 54 legumes in the database, hyacinth beans ranks 13th by protein per serving, and 229th out of all 796 foods on the site. Set against split peas, another legume entry in the database, a serving carries about 0.5 g less protein (split peas has 16.3 g per 1 cup cooked).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is measured by volume at 194 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
